46 times 1 is 46, but what is the answer if both 46 and 1 are negative numbers? Here we will determine if the answer to negative 46 times negative 1 is positive 46 or negative 46.
There are many different ways to explain and determine if the answer to negative 46 times negative 1 is -46 or +46 using mathematical terms such as additive inverse and mathematical laws like the Distribute Law.
We will take a different approach - process of elimination: We will simply test if -46 is the correct answer using basic algebra.
We will test if -46 is correct by setting up the equation negative 46 times negative 1 equals negative 46, and then simplifying the equation to see if it is true.
(-46) (-1) = (-46)
Divide both sides of the equation by (-1) :
|
| = |
|
The numerator and denominator on the left side both have (-1) which even each other out and can be removed:
| (-46) = |
|
The numerator and denominator on the right side both have a minus sign (-) which even each other out and can be removed:
| (-46) = |
|
A numerator of 46 and denominator of 1 on the right side is the same as 46 divided by 1 which is 46. Now we end up with this untrue equation:
(-46) = (46)
-46 is NOT equal to 46, thus we have proven that negative 46 times negative 1 is not equal to -46. The answer must therefore be 46:
-46 x -1 = 46
The above applies to all math problems where you multiply two negative numbers. Multiplying two negative numbers such as negative 46 times negative 1 will always have a positive answer.
